Description

Technical Field

[0001] The utility model relates to the field of logistics transportation, in particular to a downhill buffer device for a logistics trolley. Background Art

[0002] A logistics trolley is a hand tool specially used for handling and transporting goods, and is widely used in warehouses, supermarkets, factories and other places. It is usually made of metal or plastic and is sturdy and durable. The design of a logistics trolley usually includes a flat plate or basket for placing goods, and two or four wheels for easy pushing and pulling. Some advanced logistics trolleys may also be equipped with a folding function or a handle with adjustable height to meet different usage requirements. In modern logistics management, logistics trolleys are an important tool for improving efficiency and saving manpower. In the process of using trolleys, it is inevitable to encounter downhill sections. Since the trolley itself will generate a large impact force during the downhill process, if the impact force of the trolley is not eliminated in time, the trolley will lose its control ability, thereby causing a safety hazard to the trolley when going downhill. For this reason, we propose a downhill buffer device for logistics trolleys. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a downhill buffer device for a logistics vehicle, which has the following beneficial effects:

[0017] 1. The downhill buffer device of the logistics trolley uses the impact force of the logistics trolley when it slides down and the turntable on the logistics trolley to impact the cylinder. At the moment of contact with the cylinder, the bottom of the cylinder begins to tilt to one side due to the impact force of the logistics trolley when it slides down. The cylinder drives the hinge to tilt to one side through the cross bar, and the hinge drives the two sets of swing plates to rotate on the horizontal axis and tilt to one side. Through the inclination of the two sets of swing plates, the top of the swing plate pulls the tension spring to begin to deform and lengthen, which can well reduce the force of the logistics trolley when it impacts downward, prevent the excessive impact force when the logistics trolley slides down and cause damage to the objects in the logistics trolley, and effectively protect the safety of the objects in the logistics trolley.

[0018] 2. The downhill buffer device of the logistics trolley contacts the cylinder through the turntable. After offsetting the impact force, the turntable on the logistics trolley slides on the cylinder, reducing much of the impact force and ensuring that the impact force of the logistics trolley is reduced to a minimum when it continues to slide down.
